Superintendent, Mass. Correctional Institution at Walpole V. Hill - Opinion of The Court

Opinion of The Court

Justice O'Connor wrote for the majority. The Commonwealth first contended that due process did not require judicial review of the prison board's decision. The Court explained that because Massachusetts law afforded judicial review of decisions of the prison board, and there was no indication that that judicial review did not extend to federal constitutional claims, there was no need to decide whether the Due Process Clause of the Fourteenth Amendment required judicial review of the prison board's decisions in the event that state law did not so provide.

The Commonwealth also did not challenge the Supreme Judicial Court's holding that Massachusetts law gave rise to a liberty interest in good-time credits that was protected by the Due Process Clause. Instead, the Commonwealth challenged the court's holding that due process required the board's decision to be supported by "some evidence", rather than simply that the board's action not be "arbitrary and capricious". The Court therefore proceeded on the assumption that there was, in fact, a liberty interest in the accumulation of good-time credits, and turned to the "nature of the constitutionally required procedures".

In Wolff v. McDonnell, 418 U.S. 539 (1974), the Court had held that when a prison disciplinary hearing might result in the loss of good-time credits, due process required that the prison notify the prisoner in advance of the hearing, afford him an opportunity to call witnesses and present documentary evidence in his defense, and furnish him with a written statement of the evidence relied on and the reason for the disciplinary action. The Court reasoned that an "inmate has a strong interest in assuring that the loss of good time credits is not imposed arbitrarily", and simply requiring "a modicum of evidence to support a decision to revoke good time credits will help to prevent arbitrary deprivations without threatening institutional interests or imposing undue administrative burdens". "Some evidence" simply means that there is "evidence in the record that could support the conclusion reached by the disciplinary board".

The Court then held that the "some evidence" standard had been satisfied in this case. The guard's testimony that, "upon investigating discovered an inmate who evidently had just been assaulted" and "saw three inmates walking away", was sufficient to satisfy the "some evidence" standard. This was so even though there was no direct evidence to suggest that either Hill or Crawford were the ones who had assaulted the victim. Nevertheless, the Court concluded that "the record is not so devoid of evidence that the findings of the disciplinary board were without support or otherwise arbitrary".
